IR2121PBF Description

Short technical summary and product information.

The IR2121PBF from Infineon Technologies is a high-speed power MOSFET and IGBT driver featuring an integrated over-current limiting protection circuit. This monolithic IC utilizes Latch immune CMOS technology for rugged construction. Its logic inputs are compatible with standard CMOS or LSTTL outputs down to 2.5V logic.

 

The driver is designed for low-side configurations and supports N-channel power MOSFETs or IGBTs. Key features include a gate drive supply range of 12V to 18V, undervoltage lockout, and a current detection and limiting loop to protect the driven power transistor. An error lead indicates fault conditions and programs shutdown time. The output is in phase with the input.

 

This device is available in an 8-PDIP package with through-hole mounting. It operates within a wide temperature range of -40°C to 150°C (TJ). The IR2121PBF is suitable for applications requiring robust gate driving with integrated protection.
